"Madhya Pradesh voting is likely to exceed 71 percent, the highest ever turnout in the state," Deputy Election Commissioner Sudhir Tripathi told the media in New Delhi.
Voter turnout till 5 p.m. -- when the polling centres closed -- was 65.45 percent.
Bharatiya Janata Party's Sushma Swaraj, leader of the opposition in the Lok Sabha, tweeted after balloting ended that her party would get another five-year term to govern Madhya Pradesh.
"I am sure the BJP will win with a huge margin in Madhya pradesh, bigger than last time," she said.
